Well, based on the usefulness of the OEM Audi Parts list, I'm starting an aftermarket parts list. This will grow over time, so as folks have ideas or find things, let me know and I'll edit this top post.
To be clear, I am not favoring any brand or supplier. These are in no particular order...

I've been adding mods today and realised that we have no comprehensive list of codes on this forum.
So here is the full list (as of right now), they have been checked however I hold no responsibility if you mess up!
I'll keep adding them as new ones are found
Please post any others I've...

Seeing as we are locked away for the foreseeable future. What mods are you doing if any?
I have decided to upgrade my sub and some other bits like fixing some issues with my RSNAV
So curious to see what others are doing if anything?
